AMERICAN SPECIFICATION forming part of Letters Patent No. 659,025, dated October :2, 1900. Application filed March 22, 1900. Serial No. 9,815. No model.)

To all whom it may concern.-

Be itknown that we, ERNST WILHELM GER- BRAOHT, residing at New York city, borough of Brooklyn, county of Kings, State of New- York, and JOHN R. OKELL, residing at Philadelphia, county of Philadelphia, State of Pennsylvania, citizens of the United States, have invented certain new and useful Im provements in Sack Fillingand Closing Machines, of which the following is a specification.

Ourinvention relates to an apparatus which has for its purpose to rapidly fill sacks or bags of textile material with'powdered or granular substances and to close such sacks or bags after they are filled.

Our invention further relates to various details of construction of the machine and its parts, all of which will be set forth in the specification and afterward pointed out in the claims.

In the drawings similar numerals indicate like parts.-

Figure l is a side sectional elevation taken on the line X X of Fig. 3. Fig. 2 is a rear'view looking from the right of Fig. 1. Fig. 3 is a plan view. Fig. 4 is a view in perspective from the front of the sewing-machine, showing the sewing-machine and thread-cutter. Fig. 5 is an enlarged vertical section of the sack-holder.

In the drawings, 5 represents a vertical frame which supports the sack or'bag holder 6 and also the platform 7, which latter is elevated above the floor 8. The employee who operates the sack or bag holder is usually seated upon the platform/7.

9 represents the delivery-chute of'any suit able device for weighing and delivering the powdered. or granular substances. under the delivery-chute of the weighing apparatus is a sack or bag holder 6. The sack or bag holder consists of two partsan inner fixed part 6 and an outer movable part 6 Each part has an end and two sides, and the sides of the outer part 6 overlap the sides of the inner part 6*. The inner part (i is rigidly secured to a strap 10, depending from the transverse portion 5 of the frame 5. The

outer part 6 is pivoted at its top to the inner part 6*. cut away,- as shown in the vertical section,

Situated part 6, so that the outer part 6 can swing inward toward and outward from the inner The sides of the inner part 6 are Fig. 5, so as to permit of the approach of the outer part 6 r The upper edge'of the part 6 is flared outwardly, and the lo WQROdgGS of the parts 6 and 6 are turned outward to form projecting flanges 6, over which the mouth fof the sack or bag is drawn and with which the material of the sacks or bags engages when the mouth of panded.

Rigidly attached to the outer movable partthe sack or bag holder is ex- 6 is an arm 11, on which is mounted an adjustable weight 12. Pivoted to a hanger 13, which depends from the transverse portion 5 of the frame, is a lever 14, one end of which is con- 'nected through the strap 15, adjustable in length, witha treadle 16, located on the platform-7. ;wheel 17, which lies under the arm'll. mally through the action of the weight 12 On the other end of the lever 14 is a N orthe movable portion 6 of the sack-holder is thrown outward and occupies the position shown in the full lines. When, however, the foot-treadle 16 is depressed, traction is made lthrough the strap 15 upon the lever 14, which causes the end of the lever carrying the wheel 17 to move upward under the bar 11 and lift the bar upward, thereby moving the outer portion 6 into the ted lines. When the parts-of the sack or-bag holder 6 are in the position shown in the dotted lines, Fig. l-that is, with the mouth of the sack or bag contracted a sack or bag 18, formed of muslin or other suitable material, may be put position shown in the dotover the flanges 6 of the inner and outer portions 6 and 6*, after which when the treadle 1b is released the bar 11 and weight l2 will descend, and thereby move the movable part 6 outward, which causes the portion of the flange 6 attached to the outer part 6 to distend theneck of the sack or bag 19 and exert sufficient pressure on it to hold the sack or bag upon the flange 6 under the strain of the weight of the granular matter contained in the sack or bag.

Connected to one of the uprights of the frame 5 is a tubular chute 20, the ends of the horizontally-reciprocating arm 59, on the which are open and one side cut away at 21. Arranged under the lower end of the chute is a shaker 22. The shaker consists of a horizontal table portion 23, which is perforated, as at 24, and a vertical supporting portion 25, located in and adapted to have a vertical motion relative to the slot-ted upright 26, which is secured to the floor at 27. The slotted upright 26 has a horizontalexlensiou 28, and secured therein is a rod 29, which extends downward and is carried through an opening (not shown) in the horizontal extension of the vertical portion 25 of the shaker.

Located and secured between the horizontal extension 28 of the upright and the horizontal extension 25 of the vertical portion of the shaker is a spring 30. This spring normally supports the shaker in its lowest position and retracts the shaker to that position after it has been moved. The upright portion 26 of the shaker is cut away at 31 to form a shoulder or surface, under and against which a toothed cam 32 may strike and act. The cam 32 is mounted upon a shaft 33, which also carries a worm-wheel 34, fixidly secured thereto. This worm-wheel takes in a worm 35 upon a shaft 36, which receives its motion from a power-belt 37. The rotation of the cam lifts the shaker 22 and the retractile action of the spring 30 and gravity returns it to its original position, the motion being quick and sudden.

Underneath the horizontal portion 23 of the shaker is a chute 38, which communicates with abin. (Notshown.) Anymaterial which may fall upon the table of the shaker, owing, for instance, to a sack or bag not being properly attached to the sack or bag holder or the breaking of a sack or bag, passes through the perforations of the table and will be carried by the chute to the bin.

Located in front of frame 5 is a second frame 39. Mounted in the sides of the upper portion of this frame in suitable bearings are the shafts and 41, which carry pulleys 42 43, over which is stretched an endless couveyer-belt 44. Mounted on the end of the shaft 40 and secured thereto is a worm-gear 45. This worm-gear meshes with a worm 46 on the shaft 47. The shaft 47 receives its motion, which is transmitted to the conveyerbelt 44, through a belt 48, passing over a pulley 49 on the shaft 50. The shaft 50 receives its motion from the power-belt 51.

52 is a sewing-machine, which may be of any suitable type. The sewing machine shown is arranged to have its needle 53 move horizontally. \Ve consider this position the best for the purpose; but we do not wish to be confined to a sewing-machine which sews horizontally. Motion is communicated to the seW- ing-machine through the belt 54, and pulleys 55 and 56.

57 is a thread-bobbin for the sewing-machine. Mounted in front of the sewing-machine is a thread-cutter 58, which consists of forward end of which is a knife-blade 60.

61 is a plate fastened to the standard of the sewing-machine, against which the knifeblade of the cutter strikes when cutting the thread. The knife-blade is normally retracted by means of a spring 62. Forward motion is given to the cutter by means of the lever-arm 63, which is pivoted to the machine at 64 at one end and attached to the chain 65 at the other end. The chain 65 is connected to a foot-treadle, (not shown,) whereby the operator can actuate the cutter at the required moment.

The sewing-machine, it will be observed, is located immediately over the conveyer-belt 44, and in designing our improved machine it is our intention that the conveyer-belt shall have a movement corresponding to the feed of the sewing-machine.

The operation of our machine is as follows: An operator sitting on the platform 7 depresses the treadle 16, which throws up the lever 14, thereby carrying upward the arm 11 and moving inward the outer portion 6 of the sack or bag holder. The operator now places the neck of the sack or bag over the contracted mouth of the sack or bag holder and over the flanges thereon and then releases the lever. At this moment the chute 9 of a weighing-machine (not shown) automatically discharges the weighed material into the sack or bag. The operator then again depresses the foot-treadle, which operation again contracts the mouth of the sack or bag holder by moving the movable portion inward, which releases the sack or bag and causes it to drop onto the shaker 22, which serves to shake the material down into the sack or bag. The operator then takes the sack or bag through the opening 21 in the chute 20 and places it upon the conveyer-belt 44, by which it is carried to the sewing-machine. A second operator at the sewing-machine seizes the sack or bags as they are brought in front of her and closes the mouth of the sacks or bags by drawing the flexible material of which they are made outward in a line parallel with the axis of the conveyer and guides the top of the sack or bag between the needle and the feed of the sewing-machine, holding the sack or bag at the time on either side of the top. As the feed of the sewing-machine and the conveyer is the same, the sack or bag will be moved forward uniformly at top and bottom and its top sewed together. When the end of the sack or bag has passed the sewing-machine, the second operator depresses a treadle attached to the chain 65, which causes the cutter to move forward and cut the thread. The filled and sewed sack or bag is then dropped by the operator into a suitable chute, by which it is conveyed to the packing department.

We make no claim in this application to the construction of a sack or bag holder consisting of a funnel having a pivoted portion or flap and a weighted external arm for maintaining the same in an extended position, as such construction has been made the subject of certain claims in another application filed by us on March 22, 1900, Serial No. 9,814.
